start time optimization of biologics in polyarticular jia

Conditions: Polyarticular Juvenile Rheumatoid Arthritis; Arthritis, Juvenile Idiopathic

Summary: stop-jia is a pcori funded prospective observational study which compared the clinical effectiveness and impact on patient reported outcomes of 3 childhood arthritis \& rheumatology research alliance (carra) consensus derived treatment strategies (ctps) in new-onset polyarticular jia (pjia) patients to answer the critical question of when is the best time to begin biologic medications to achieve the optimal clinical and patient reported outcomes. because the carra registry will be used for data collection, all patients will be enrolled in the carra registry. the standard of care treatments are chosen by the treating physician and patient/caregiver and are not randomized.

stop-jia is a prospective, observational study comparing the clinical effectiveness and impact on patient reported outcomes of 3 different treatment strategies (ctps) in new onset pjia patients to answer the critical question of when to start biologic medications. all participants will be enrolled in the carra registry and started on one of the ctps, which will be decided by the treating physician and patient/caregiver. subjects will be enrolled at one of 60 participating carra sites across the us and canada. total anticipated enrollment was 400 and this was completed in 9/19. specific aim 1: to compare the clinical effectiveness of different strategies (ctps) for using biologic medications in achieving clinically inactive disease (cid) at 12 months in new-onset pjia. three common strategies that differ in the timing of biologic medication introduction will be compared: 1) step-up: disease modifying anti-rheumatic drug (dmard) monotherapy stepping up by addition of a biologic medication if needed; 2) early combination: dmard plus biologic medication at treatment onset; and 3) biologic first: biologic medication monotherapy at treatment onset. hypothesis 1: a significantly higher proportion of children started on a biologic medication at onset (ctp 2 or 3) will achieve cid after 12 months of therapy compared to standard therapy (ctp 1). specific aim 2: to compare patient and caregiver reported outcomes between the different strategies. hypothesis 2: there will be statistically significant differences in patient/caregiver reported outcomes (pros) between treatment strategies that can inform future patients and providers in selecting optimal treatments. the carra registry will be housed at carra's clinical and data coordinating center, duke clinical research institute (dcri). the carra registry protocol documents that the carra registry fulfills all pcor standards for registries. stop-jia will utilize data collection, storage, and management processes, systems requirements, and security processes already established for the carra registry at dcri. stop-jia used web-based electronic crfs (ecrfs) developed for the carra registry that are already familiar to site personnel. the ecrf platform, rave, is 21cfr part11 compliant and meets regulatory requirements. database and web servers are secured by a firewall and through controlled physical access. ecrfs will be monitored for completeness, accuracy, and attention to detail throughout the study by dcri data and site management teams using processes developed for the carra registry and consistent with dcri's internal sops. use of electronic data capture will allow for immediate prompts/queries if entered values are out of expected ranges or there are incomplete data fields. the design of the data collection instrument will allow centers to record a planned assessment of a patient was missed and to enter any known reasons for the assessment being missed. dcri will regularly provide reports detailing data completion metrics to the sites. stakeholder engagement is also an important aspect of this study, and patients/caregivers as well as other stakeholders are serving as research partners and advisors in this study.
